Abstract

A toner collecting tray (10) for a photocopier collects the toner removed from the process drum and when full is disposed of and replaced by a fresh tray. The tray is made of non-ferromagnetic material and fits over the magnetic collecting roller (5), to enclose the roller. A scraper (2) loosens the toner and the rotation of the magnetic roller moves the toner over the surface of the non-ferrous tray into the reservoir. The tray is totally enclosed, save for the scraper slit. The movement of the toner follows the rotation of the magnetic roller and causes swirling inside the reservoir, to aid stacking of spent toner. The tray is removed by pulling it over the magnetic roller, with a min. of spillage. The tray (10) and the tube (7), which fits over the roller, are made from the same piece of material.

Description

Beschreibungdescription

Die Erfindung betrifft eine Vorrichtung nach dem Gattungsbegriff des Anspruches 1. The invention relates to a device according to the generic term of claim 1.

Bei diesem Gerät zieht die Magnetwalze den sich vor dem Abstreifer ansammelnden ferromagnetischen Toner auf ihre Oberfläche und transportiert ihn vom Prozeßzylinder fort. Durch weitere Maßnahmen wird der Toner in einen Auffangbehälter transportiert. In this device, the magnetic roller pulls itself in front of the scraper ferromagnetic toner accumulating on its surface and transporting it off Process cylinder away. Further measures will put the toner in a collecting container transported.

Bei diesen Geräten ist das Wegtransportieren des Toners von der Magnetwalze aufwendig, da die Magnetwalze ständig bestrebt ist, den Toner wieder anzuziehen. With these devices, the toner is transported away from the magnetic roller expensive, since the magnetic roller constantly strives to attract the toner again.

Aufgabe der Erfindung ist es, die Transportvorrichtung so auszubilden, daß der Transport des Toners ohne Blockieren der Transportfunktion der Vorrichtung durch angesammelten Toner erfolgt. The object of the invention is to design the transport device in such a way that that the transport of the toner without blocking the transport function of the device caused by accumulated toner.

Diese Aufgabe wird durch das kennzeichnende Merkmal des Anspruches 1 gelöst. This task is achieved by the characterizing feature of the claim 1 solved.

Bei der erfindungsgemäßen Ausbildung zieht die Magnetwalze, wie auch bei den bekannten Geräten, den sich vor dem Abstreifer ansammelnden Toner an. Da die Magnetwalze allseitig von einem nichtferromagnetischen Rohr umgeben ist, bleibt der Toner auf der Oberfläche dieses Rohres haften. Wird die Magnetwalze jedoch gedreht, wandert der Toner auf der Oberfläche des Rohres entgegengesetzt zur Drehrichtung der Magnetwalze. Da sich an das Rohr ein Auffangbehälter anschließt) trifft der Toner schließlich auf den Teil des Auffangbehälters, der diesen mit dem Rohr verbindet. In diesem Bereich zeigt sich nunmehr, daß sich der Toner nicht anhäuft, sondern er wandert längs des Behälterbodens von der Wandung weg. Dies geschieht jedoch nur im Bereich des Magnetfeldes der Magnetwalze. Außerhalb dieses Bereiches bleibt der Toner liegen und wird angehäuft. Im Behälter wird dadurch eine günstige Volumenausnutzung erreicht, da sich ohne diesen Effekt lediglich eine Anhäufung von abfallendem Toner unterhalb des Rohres bilden würde. In the embodiment according to the invention, the magnetic roller pulls, as well in the known devices, the toner that collects in front of the wiper. There the magnet roller is surrounded on all sides by a non-ferromagnetic tube, remains the toner will stick to the surface of this tube. However, if the magnetic roller is rotated, the toner migrates on the surface of the tube opposite to the direction of rotation the magnetic roller. Since a collecting container is attached to the pipe) the Finally, toner on the part of the collecting container that connects it to the tube. This area shows now that the toner does not accumulate, but it wanders away from the wall along the bottom of the container. this happens but only in the area of the magnetic field of the magnet roller. Outside of this range the toner remains and is piled up. This makes a cheap one in the container Volume utilization is achieved, since without this effect there is only an accumulation of falling toner would form underneath the tube.

Die erfindungsgemäße Ausbildung bringt den weiteren Vorteil, daß der Behälter flach und langgestreckt sein kann, was sich konstruktiv für ein flaches Kopiergerät günstig auswirkt. The inventive training has the further advantage that the container can be flat and elongated, which is constructive for a flat one Copier has a beneficial effect.

In weiterer Ausgestaltung der Erfindung ist das Rohr mit dem Auffangbehälter allseitig geschlossen ausgebildet und nur zum Abstreifer hin ist eine Schlitzöffnung vorgesehen, durch die der Toner in den Behälter eintritt. Ein solcher Behälter kann komplett aus dem Gerät herausziehbar sein, so daß er gegen einen neuen Behälter mit Rohr ausgewechselt werden kann. In a further embodiment of the invention, the pipe is with the collecting container Formed closed on all sides and only towards the scraper is a slot opening provided through which the toner enters the container. Such a container can be completely removable from the device, so that it is against a new container can be exchanged with tube.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. An exemplary embodiment of the invention is shown in the drawing.

Auf dem Prozeßzylinder 1 gleitet ein Abstreifer 2, der den auf der Oberfläche des Prozeßzylinders 1 noch haftenden Toner 3 vor sich sammelt. Der Prozeßzylinder 1 ist in Richtung des Pfeiles 4 drehbar. Unmittelbar vor dem Abstreifer X ist parallel zum Prozeßzylinder eine Magnetwalze 5 angeordnet, welche axial parallel angeordnete Nord- und Südpole N, S trägt. Die Magnetwalze ist in Richtung des Pfeiles 6 drehbar, also entgegen -etzt zum Prozeßzylinder 1. Die Magnetwalze S ist von F'.Lem nichCerromagnetischen Rohr 7 umgeben. Der sich vor dem Abstreifer 2 ansammelnde Toner wird von der Magnetwalze angezogen und haftet zunächst auf dem Rohr 7. Dreht man die Magnetwalze in Richtung des Pfeiles 6, dann wandert der Toner auf dem Rohr 7 in Richtung des Pfeiles 8. Das Rohr 7 ist mit der vorderen Wandung 9 des Auffangbehälters 10 verbunden. Der in Richtung des Pfeiles 8 um das Rohr laufende Toner trifft auf die Wandung 9 und gelangt auf den Boden 11 des Behälters. Hier wandert der Toner zunächst in Richtung des Pfeiles 20. Außerhalb des Magnetfeldes der Magnetwalze bildet sich durch ständige Tonerzufuhr eine Aufschüttung. On the process cylinder 1 slides a scraper 2, which is on the Surface of the process cylinder 1 still adhering toner 3 collects in front of it. The process cylinder 1 can be rotated in the direction of arrow 4. Immediately in front of the scraper X is parallel to the process cylinder a magnetic roller 5 is arranged, which is axially parallel North and South poles N, S carries. The magnetic roller can be rotated in the direction of arrow 6, thus opposite to the process cylinder 1. The magnet roller S is not ferromagnetic from F'.Lem Surrounding tube 7. Which Toner accumulating in front of the wiper 2 is attracted by the magnetic roller and initially sticks to the pipe 7. If you turn the magnetic roller in the direction of arrow 6, then the toner migrates on the tube 7 in the direction of arrow 8. The tube 7 is with the front wall 9 of the collecting container 10 connected. The toner running around the tube in the direction of arrow 8 hits the wall 9 and reaches the bottom 11 of the container. This is where the toner wanders first in the direction of arrow 20. Outside the magnetic field of the magnetic roller The constant supply of toner creates an embankment.

Diese Aufschüttung wächst, wie durch die Pfeile 21 bis 27 angegeben, um schließlich den Behälter bis zur Aufschüttung 30 aufzufüllen.This embankment grows, as indicated by arrows 21 to 27, in order to finally fill the container up to the embankment 30.

Man erkennt, daß bei dieser Ausbildung der Auffangbehälter 10 in sich geschlossen und flach gehalten werden kann. It can be seen that in this design, the collecting container 10 in can be kept closed and flat.

Die Abdeckung des Behälters umschließt mit einer schmalen Uffnung einen Teil des Rohres 7, so daß hier durch magnetische Wirkung beim Kippen oder Schwenken des Gerätes kein Toner herausfallen kann.The cover of the container encloses with a narrow opening part of the tube 7, so that here by magnetic action when tilting or If the device is swiveled, no toner can fall out.

Diese Öffnung dient bei dem sonst geschlossenen Behälter als Tonereintrittsöffnung. This opening serves as a toner inlet opening in the otherwise closed container.

Der Behälter 10 und das Rohr 7 bestehen aus einem Stück. The container 10 and the tube 7 consist of one piece.

Beide Teile sind gemeinsam aus dem Gerät herausziehbar, so daß dann, wenn der Behälter 10 gefüllt ist, dieser in einfacher Weise durch einen neuen leeren Behälter ersetzt werden kann. Der Behälter 10 und das Rohr 7 sind zweckmäßigerweise als Wegwerfbehälter ausgebildet, da der im Behälter angesammelte Toner ohnehin verschmutzt ist und nicht mehr wiederverwendet werden kann.Both parts can be pulled out of the device together, so that when the container 10 is full, empty it in a simple manner with a new one Container can be replaced. The container 10 and the tube 7 are expedient designed as a disposable container, since the toner accumulated in the container is dirty anyway and can no longer be reused.
